c# - Cannot find the interop type'Microsoft.Internal.VisualStudio.Shell.Interop.SVsColorThemeService' -


i building visual studio package/extension using visual studio 2013 update 4 community edition. using standard project template comes visual studio sdk under extensibility projects group. enter image description here

what need svscolorthemeservice when add following line in initialize method

 var svc = getglobalservice(typeof(svscolorthemeservice)) ivscolorthemeservice;

i 2 build errors:

cannot find interop type matches embedded interop type 'microsoft.internal.visualstudio.shell.interop.svscolorthemeservice'. missing assembly reference?  cannot find interop type matches embedded interop type 'microsoft.internal.visualstudio.shell.interop.ivscolorthemeservice'. missing assembly reference?

enter image description here

the referenced assemblies not touched @ all.

so looking svscolorthemeservice decompiler finds in 

// decompiled jetbrains decompiler // type: microsoft.internal.visualstudio.shell.interop.svscolorthemeservice // assembly: microsoft.visualstudio.shell.12.0, version=12.0.0.0, culture=neutral, publickeytoken=b03f5f7f11d50a3a // mvid: b8fca7e4-7d13-4e4b-a74b-6b6b01263daf // assembly location: c:\program files (x86)\microsoft visual studio 12.0\vssdk\visualstudiointegration\common\assemblies\v4.0\microsoft.visualstudio.shell.12.0.dll  using system.runtime.compilerservices; using system.runtime.interopservices;  namespace microsoft.internal.visualstudio.shell.interop {   [compilergenerated]   [interfacetype(cominterfacetype.interfaceisiunknown)]   [typeidentifier]   [guid("0d915b59-2ed7-472a-9de8-9161737ea1c5")]   [comimport]   public interface svscolorthemeservice   {   } }

enter image description here

as can see assembly referenced. question how hold of svscolorthemeservie , use proper way?

edit1: after research , following @simon mourier suggestion i've added following code solution:

using system; using system.runtime.compilerservices; using system.runtime.interopservices;  namespace microsoft.internal.visualstudio.shell.interop {     [comimport]     [guid("0d915b59-2ed7-472a-9de8-9161737ea1c5")]     [interfacetype(cominterfacetype.interfaceisiunknown)]     public interface svscolorthemeservice     {     }      [comimport]     [guid("eab552cf-7858-4f05-8435-62db6df60684")]     [interfacetype(cominterfacetype.interfaceisiunknown)]     public interface ivscolorthemeservice     {         ivscolortheme currenttheme { get; }          ivscolorthemes themes { get; }          void _vtblgap1_4();         void _vtblgap2_1();     }      [comimport]     [guid("98192afe-75b9-4347-82ec-ff312c1995d8")]     [interfacetype(cominterfacetype.interfaceisiunknown)]     public interface ivscolorthemes     {         ivscolortheme getthemefromid([in] guid themeid);     }      [comimport]     [guid("413d8344-c0db-4949-9dbc-69c12badb6ac")]     [interfacetype(cominterfacetype.interfaceisiunknown)]     public interface ivscolortheme     {         guid themeid { get; }          void _vtblgap1_1();          void apply();     } }

what provide missing interfaces com objects. still won't build, throwing same errors + warmings conflicting types.

warning 3   type 'microsoft.internal.visualstudio.shell.interop.ivscolortheme' in 'c:\users\codemaster\documents\visual studio 2013\projects\vspackage1\vspackage1\class1.cs' conflicts imported type 'microsoft.internal.visualstudio.shell.interop.ivscolortheme' in 'c:\program files (x86)\microsoft visual studio 12.0\vssdk\visualstudiointegration\common\assemblies\v4.0\microsoft.visualstudio.shell.12.0.dll'. using type defined in 'c:\users\codemaster\documents\visual studio 2013\projects\vspackage1\vspackage1\class1.cs'.    c:\users\codemaster\documents\visual studio 2013\projects\vspackage1\vspackage1\class1.cs   19  9   vspackage1

some types in vs assemblies require other assemblies (pia). explained here: troubleshooting errors when embedding type information (doug rothaus).

in visual studio specific case, don't know how solve (where assemblies?) other recreate types manually (hint: use tools .net reflector in matter because dll contain definition). example, here how compile code, add somewhere:

namespace myinterop {     [comimport, interfacetype(cominterfacetype.interfaceisiunknown), guid("0d915b59-2ed7-472a-9de8-9161737ea1c5")]     public interface svscolorthemeservice     {     }     [comimport, interfacetype(cominterfacetype.interfaceisiunknown), guid("eab552cf-7858-4f05-8435-62db6df60684")]     public interface ivscolorthemeservice {         void _vtblgap1_4();         ivscolorthemes themes { [return: marshalas(unmanagedtype.interface)] get; }         ivscolornames colornames { [return: marshalas(unmanagedtype.interface)] get; }         ivscolortheme currenttheme { [return: marshalas(unmanagedtype.interface)] get; }     }     [comimport, interfacetype(cominterfacetype.interfaceisiunknown), guid("98192afe-75b9-4347-82ec-ff312c1995d8")]     public interface ivscolorthemes {         [return: marshalas(unmanagedtype.interface)]         ivscolortheme getthemefromid([in] guid themeid);     }     [comimport, guid("413d8344-c0db-4949-9dbc-69c12badb6ac"), interfacetype(cominterfacetype.interfaceisiunknown)]     public interface ivscolortheme {         void _vtblgap1_1();         ivscolorentry this[colorname name] { [return: marshalas(unmanagedtype.interface)] get; }         guid themeid { get; }     }     [comimport, typeidentifier, interfacetype(cominterfacetype.interfaceisiunknown), guid("bbe70639-7ad9-4365-ae36-9877af2f973b")]     public interface ivscolorentry {         colorname colorname { get; }         byte backgroundtype { get; }         byte foregroundtype { get; }         uint background { get; }         uint foreground { get; }     }     public struct colorname {         public guid category;         [marshalas(unmanagedtype.bstr)]         public string name;     }     [comimport, interfacetype(cominterfacetype.interfaceisiunknown), guid("92144f7a-61de-439b-aa66-13be7cdec857")]     public interface ivscolornames {         void _vtblgap1_2();         int count { get; }         system.collections.ienumerator getenumerator();     } }
